- Ferry crossing from Bali to Ketapang port
- Guided trek with experienced local mountaineer
- Breakfast included before the climb
What to expect
You'll depart Bali in the evening and cross by ferry to East Java, arriving at the trailhead around midnight. The 2-3 hour ascent starts in darkness; your guide carries a lamp. Temperatures drop considerably at altitude. Once at the rim, you'll observe the blue flames—caused by ignited sulfurous gases—and wait for dawn to break over the crater and surrounding peaks. The descent takes roughly 2 hours. Expect volcanic rock underfoot, thin air at height, and substantial physical exertion. This isn't a gentle walk.
Good to know
Minimum moderate fitness required. Not suitable for pregnant travellers, those with spine injuries, or cardiovascular concerns. Wear sturdy hiking boots, warm layers, and a headtorch. Guide and driver tips aren't included. Ferry schedules may shift seasonally—confirm timing when booking.
